1To aZZ whom, t concern: i

Be it Yknown ,that I, GHANA H. Barcos, a citizen lof the United States, residing at y,Little Rock, in the county of Pulaski andl State of Arkansas, have vinvented certain new and useful Improvements in Type-Bar- Casting Molds; and I dohereby :declare the following to be a vfull'clear, and exact description l of the invention, such as will enable othersskilled inthe art to which appertains to make and .use the same.

The present invention relates to improvements'in linotype molds and more particularly resides in a` mold for use in produc-ing 18 point slugs, such as used in brief work, in which italics :are largely employed land wherein the lines must be double spaced to iliary faces of duplexmatrices does not permit the casting of the two incombination on one slug 18 points thick with the ordinary mold. The improvedfmold engages the mats in such a way as to cast the type faces 4 Vpoints low on the slug and this 4c points added to the ordinary 14 point slug gives the 18 point slug. v

The advantage accruingis the setting of the matter slugged out and the invention obviates ,the process of slugging out subsequently and pulling the slugs after the `printing Vandfbef'ore 'dumping'.

The use .of the invention enables me to print law briefs spaced properly without slugging out to 18 points to the line and further enables me to use italics with roman letters, as Ais'necessary in brief composition, while still retaining and preserving the correct alinement of the letters.

With the foregoirg'fand other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claim appended heretoy yIn, the drawings, wherein like symbols refer to like or corresponding parts through- Aout the several views,

so ltion and showing the'chan'ges byIcomparison.l

Figure 1 is a similar viewV showing the`v -v ,elevator4 and mat in the raised position for 'casting ythe other type face.-

a Figure 5 is a comparative sectional view showing the matin the position indicated 1n F igureB'b-ut with the changes according to the present invention, and Y Figure 6 is a similar sectionalfview comparative with arespect to Figure Li'and lshow-y ing the 18 point arrangement.

Referring more particularly to the drawling 1designates generally the .mold body and Qthe cap piece therefor which are fitted removably together and provide the mold cavity 3 in which the slug is cast. The molds are carried in suitable number upon theA casting wheel .in laccordance with va .well

known ,practice and the mold cooperates i with .the first elevator, a portion of which is represented at 4 and which carriesv the matsor matrices `5 to' enable the facesor die-cavities thereofto be brought intoI registry with one end .portion of themold cavity 3. -vThe other Aend of `the cavity or the-end portion atthe opposite edge of the vmold is in communication with a source of plastic material supply which is forced into the mold cavity and into the d i'e faces of the matrices whereby toproduce the raised type upon the outer edge of the linoty'pe slug thus cast.

A keeper 6 is `carried by the `mold body 1- to cooperate with the'lugs 7 upon themats 5 and the' keeper isi arranged below a-lip l8 uponr the mold body `1 .which is directly vbelow the mold-cavity andextends outward- `ly toward the mats. A similar lip 9 is dis. ,A

mat faces are designated at 10 and these 1113) l?? @man and italic,

In Figure l, end-liners 12 and 13 are shown which close the ends of the mold cavity 3. In Figure 1 the end-liners are shown to be 14 points thick or high to regulate the height of the mold cavity and the thickness or height of the slug cast.

Now in law brief work this 14 point mold is usually employed but the thickness of the slug producedis not sufficient for the spacing of the lines and as a Yconsequence the objectionable and annoying process of .lea dinoutorslu ino* out results. This y is expensive and consumes la greatk deal of time. New if it were practicable to cast an 18 pointY slug, such slug would give the "required dimension for the spacing vto be secured in law brief work and would avoid .this leading out orrslugg1ng out process and the expense and annoyance incident thereto. This result I accomplish by the use of themold shown in Figures 2, 5 and 6. In accordance with the invention approximately the Vsame cap piece and mold base or body may be used and also the same keeper except for a re-positioning thereof. The end-liners 14 and 15 as shown in Figure 2 are utilized, these end-liners being 18 points in height or thickness and thus increasing the height of the mold cavity suitably for producing an 18 point slug.

Now in case an attempt was made to use standard mats in conjunction with the mold Vstructure thus varied, it would be found that the primary and auxiliary faces 10 and 11 of the mats would not register accurately with the central longitudinal portion of the slug and consequently the alinement of the type would be destroyed and the device useless for the purpose intended,

.however I remedy this situation by modifyy ing the construction of the lip 8 vupon the .body of the mold. This. lip is shown in vFigures 3 and 4 to be relatively thick but in Figures 5 and 6 in which the invention is shown, a comparatively thinlip 16 is used upon the mold body 1. The reduction in thickness of this lip is not carried out upon the upper face of the lip which is required to be continuous with the bottom wall of the mold cavity 3, but the entire reduction in thickness of lthe lip occurs at the lower portion thereof. This reduction at this particular point permits of raising the keeper 6, which is accordingly done by the use of the screwsV 17 and the slots 18. The keeper thus undergoes a re-positioning or avraising towardthe mold cavity which is permitted by the reduction in thickness of the lower portion of the lip 16 without in any wiseA modifying theY upper surface of theV lip. It will thus be noted that the elevator may be required to stop only at the higher position or a position in which the upper type face or. ldie cavity 1() is positioned centrally of the enlarged or 18 point mold cavity 3. It will be found that if the usual standard type or mold useful for molding 14 point slugs is altered bygrinding andv reducing the lower portion of the lip upon the mold body nig-6 of Van inch, the mats 5 may be raised 4 pointsy andthe type faces 10 will then arrive at a correct central position with respect to the mold cavity.

Now the invention'further involvesV a reduction or a thinning-of the upper lip 9 upon the mold cap 2. This reduced/lip is yshown at 17 in Figures 5 and6. The `'under portion ofthe lipfl? is leftv as before lto produce a proper continuation, of the/upper wall of the moldcavity and the reduction entirely takes place from above so that we have two reduced lips 16 and 17 with proximate faces as before but with outer remote portions reduced. The reduction in the upper lip 17 is such as to permit the elevator to descend as indicatedlin Figure 5 to bring the upper face of the mat correctly before the central part of the vmold opening. In Figure 6 the lug 7 upon the mat is shown engaged with the reduced under face of the lip 16 and the auxiliary face 11 of the mat 5 is shown to be in alinementl with the centralpart of the mold cavity.

Tt will b appreciated that'rthe improved y mold e involves no further parts over the old mold and that it accomplishes the 'result stated simply and inexpensively while avoiding a great part of the labor and expense heretofore 'encountered vin the` printing of law briefs and the like.

mold base having a thin lip, a keeper raised' 4 points above the normal position to the thin lip, said lip cooperating with the matrices lugs, va cap for the mold also having a thin lip to cooperate with theV elevator, and end-liners of substantially 18 pointsV between the mold base and cap.
